A new sport has taken the World by storm. With a history that diverted from ours thousands of years ago, the superpowers of today are radically different. Sioux Indians hold North America, Vikings rule much of Europe and Russia, and the Egyptians hold Africa... and for the benefit of the crowd they’re all killing each other. Huge stadiums holding hundreds of thousands of screaming fans encircle small combat arenas, where soldiers fight and die... and if you can’t hear the roar of the crowd, you’re already dead.

To me each has appealing features that would go well together. Like the shape of 1's body (minus stock), 2's stock, scope, and trigger guard, and 3's rail, magazine enclosure, and barrel. Just my opinion
